Abstract

The utility model belongs to a special medical appliance for locating and positioning during radiotherapy for head and neck tumors. The special medical appliance is provided with a square support (4) with scales, sliders (2), (5), (8), (13), (14) are mounted on the square support (4), the sliders (5), (8), (13) are respectively provided with laser lamp pointers (6), (10), (12) with scales, the laser lamp pointers (6), (12) are respectively provided with angle measurers (7), (11), and the square support (4) is further provided with level gauges (1), (3) and a laser staff (9). The head and neck precise locating and positioning instrument is mainly used for realizing precise locating and positioning during radiotherapy for head and neck tumors, and further increases tumor radiotherapy effect.

Description

The accurate localization and positioning instrument of incidence

Technical field:

The special-purpose medical apparatus and instruments of location and pendulum position when this utility model is the tumor of head and neck radiotherapy.

Background technology:

Require during the tumor of head and neck radiotherapy position is accurately located and put to incidence, some now used medical apparatus and instruments can only the method with range estimation position and put the position in a certain plane, error is very big, and the position poor repeatability is having a strong impact on the tumor radiotherapy effect.

Summary of the invention:

This utility model adopts one 5 place to have graduated square set, 2 level indicators and 5 slide blocks with sliding function are housed on support, wherein on 3 slide blocks the laser lamp pointer is housed, wherein on 2 horizontal laser light lamp pointers an angular surveying device is installed respectively, accurately make two porus acusticus externus place antimeres of patient and facial skin marker by the laser lamp pointer during location, by the angle of record canthomeatal line and vertical line, can accurately determine the position of patient's incidence; By repeating each skin marker, recover each record and realize the accurately purpose of pendulum position during the pendulum position.

Description of drawings:

Accompanying drawing is a kind of structural representation of the present utility model, in the accompanying drawing the 1, the 3rd, and level indicator, the 2,5,8,13, the 14th, slide block, the 4th, square set, the 6,10, the 12nd, be with graduated laser lamp pointer, the 7, the 11st, angular surveying device, the 9th, laser scale.

The specific embodiment:

During the location, the patient lies on the back, and selects suitable headrest, at first uses whether level of level indicator 1,3 measurement and positioning bed boards, again laser scale 9 is aimed at the indoor laser lines; Pointer 10 is aimed at the head anterior midline and is made skin marker, measures distance and the record of skin marker to slide block 8 with pointer 10;

Pointer

6,12 is aimed at the skin of bilateral porus acusticus externus place antimere respectively and is made skin marker, measure distance and the record of the skin marker of bilateral porus acusticus externus place antimere respectively with

pointer

6,12, require the scale identical and record of slide block 5,13 on support 4 to slide block 5,13; Measure the angle of patient's canthomeatal lines and vertical line and note down with angular surveying device 7,11; At last, simultaneously sliding

slider

2,14 makes level indicator 1 be close to the head fixed mount and writes down the scale of slide block 2,14.During treatment pendulum position, repeat above-mentioned each skin marker, recover each calibration record and get final product.

Claims

1. the accurate localization and positioning instrument of incidence, it is characterized in that, it is with graduated square set (4), slide block (2), (5), (8), (13), (14) are housed on the square set (4), be equipped with respectively on slide block (5), (8), (13) and be with graduated laser lamp pointer (6), (10), (12), angular surveying device (7), (11) are housed respectively on laser lamp pointer (6), (12), level indicator (1), (3) and laser scale (9) are housed on the square set (4) in addition.

2. according to claims 1 described localization and positioning instrument, it is characterized in that, slide block (2), (5), (8), (13), (14) are connected support (4) and go up also and can go up slip at support (4), can slide on the slide block at its place with graduated laser lamp pointer (6), (10), (12), angular surveying device (7), (11) can be gone up in laser lamp pointer (6), (12) respectively and be slided.
